These contamination events can drastically decrease the permeate flux, increase energy consumption, and ultimately affect the performance of the MBR system.

A plethora of strategies have been proposed to mitigate membrane fouling in PVDF-based MBRs. These strategies can be broadly categorized into proactive and restorative approaches. Preventive measures aim to reduce the formation of contaminants on the membrane surface by optimizing operational parameters such as transmembrane pressure (TMP), hydraulic retention time (HRT), and feed water quality.

Corrective methods, on the other hand, focus on eliminating existing fouling layers from the membrane surface through physical or chemical procedures. Physical cleaning methods include backwashing, air scouring, and manual abrasion, while chemical cleaning utilizes agents such as acids, bases, or enzymes to dissolve or degrade fouling materials.

The choice of mitigation strategy relies on the specific fouling mechanisms occurring in the MBR system and the operational constraints.
